To all whom it may concern Be it known that I, ALWYNE F; Jmiioes, a citizen of the United States, resi'dingfat Rochdale, county of Worcester, State of lvlassachusetts, have invented an Improvement in Carding-Machines, of which the following description, in connection with the accompanying drawing, is a specifica tion, like characters on the drawing representing like p arts.

This invention relates to improvements intextile machines such as cardingma'chines which comprise mechanism for separating the material being treated,such as a lap of carded material, into strands, orwhich maintains several strands of material in a' separated condition. I

In carding Wool, silk, and like materials and particularly in "utilizing the waste from' woolen, worsted and :silk mills, the material is passed through a carding mechanism of the usual construction havingdofiing mechanism which divides the Web of carded ina terial into a series of strands of roping which are usually carried through suitable condensers and thence through suitable guides to spooling or other winding mecha nism upon which they are wound .in the usual manner,.the spooled material being thereafter treated 1n any desired manner.

It frequentlyhappens that wandering fibers extend from one strand of roving to another, and as the several strands are being reeled upon the winding'mechanism these fibers will engage the guides which'dir'ect the strands to the winding mechanism, and frequently being of :greater strength than the strand itself will break or injure the roving. j

"@ne of the obj ectsof the present invention is to provide means which will sever the fibers connecting one strand of rovingrto another without injuringior breaking either of the strands of rov'ingto which the fiber is attached, and to accomplish; this result means have been providedi whereby such] fibers will be burned in two thus avoid ng the placing of any substantial tension upon the strands of roving to be wound.

Another object of the invention is to pro- I vide means whereby the mechanism utilized for burning off the Wandering fibers will not scorch or injure the adjacent edges of "the strands of roving;

' winding frame,

Y objects of the invention and the nature thereof will more fully appear from .the iollowing description and the accompanying drawings and will be particularly pointed out in the annexed claims.

In'the drawings, Figure 1 is an eiid view otthe'winding frame with my invention attached thereto illustrating the relative posit'iio'n er the condenser, the winding mechanism and the means for severing the Wandering fibers which extend between the strands Fig.4. Fig.6 is a perspective view of a support for the "incandescent electric element illustrated in Figs. 4 and 5. Fig. 7 is a plan view of a modified form of support for the incandescent element. Fig. 8 is a sectional view of the element illustrated in Fig. 7 taken on lines 88 of said figure.

The. preferred embodiments of my invention are illustrated herein as adapted for us'e in connection with a carding machine ofxthe usual type having one or more doilers adapted to deliver the carded material in a series ofparallel strands of roving. Inasmuch as the carding machine is of a usual construction itis not illustrated in the drawing. ,Frorn'jthe'doffers the strands of roving ar' eideliveredjto condensing aprons 1, 2, of

the usual type whence they are carried to suitable receiving" nechanism preferably a spool 3 "which is suitably'supported upon the The winding name as illustrated herein comprises vertical standards 4 having two or more lateral projections 5 provided with journals 6'adapted to support drums 7 upon which the spoolsrest and by which they are driven; Extending from the opposite side of the frame & are suitable brackets 8 which forni supports for a series of guides 9 preferably mounted in a vertical position upon a rod 10. The aforesaid mechanism is of the usual character and forms no invention. i

part of my Itis found'in practice" that 'i n' winding strands of roving of the character above de-- scribed, wandering fibers frequently extend from one strand to another, and that such fibers engaging the guides 9 as the strands are being wound upon the spool offer sufli-- cient resistance to injure or break one" or both the strands. I In the use of long wools and of wastematerial from worsted, silk, and the like ,the

roving is of a very loose character and is very easily torn apart, it'is therefore necessary that the means for severing 'the fibers connecting one strand of roving to another be of such a character as to offer practically no resistance to theforward movement of the strands. I 1 I a In the preferred embodiment of theinvention illustrated herein such .a severing means is provided by interposing an incandescent element intermediate of the strands of roving. This incandescent element may be of any well known character but is pref erably constructed of a wire having a rela tively high electrical resistance and adapted to be made incandescent by an electric current of the ordinary strength and potential. In the particular embodiments of the in-v vention illustrated in the drawings brackets 12 are suitably attached to thebracket 8, or' to. the rods 10, which may be moved back and forth, and serve to support bars 13 in front of and parallel to the guide supports: 10. The bars 13 may be of wood provided with a covering of asbestos or other insu-f lating material lt to support a series of electric conductors spaced at suitable intervals to permit" the several strands of roving to pass between them.

As illustrated in Fig. 2 the conductors 15 are in the form'of short plates having intervening spaces 16 insulating the successive blocks from one another. The ends of the conductors 15 are connected by upwardly extending loops of wire 17 of suitable material of high resistance, said. loops being located intermediate of the strands of roving 18. The end plates, 15 areconnected to binding posts 19, which are connectedby wires 20 to any suitable, source of electric energy. It will be seen that the r-several, strands of roving inpassing between these wires which are rendered incandescent by the current will be maintained wholly separated from one another since any wandering fiber which extends from one strand of roving to another upon coming in contact with an incandescent wire will be instantly burned off without creating any such tension upon the strand as to injure or destroy it.

Another embodiment of my invention is illustrated in Figs.4, 5, and 6 m which the loops of wires are arranged in p anes substantially parallel to the direction of movementof the strands of roving. In this form of my invention the supporting bar 13 may be covered with an insulating covering 14: such as asbestos as in the device shown in Figs. 2 and 3. A series of brackets or stands are'mounted upon the bar 13, such brackets or. stands being preferably in the form illustrated in Figs. 5 and 6 and comprising a body portion 21 with upwardly projecting lugs 22 containing apertures 23 for the reception of the ends of the loop of wire which constitutes the incandescent member. The lower. portion of the body 21 is preferably provided with a pair of legs 2st extending under a portion of said body intermediate of the, upstanding lugs 22. This'construction is adapted to permit a free circulation of, air about the supporting member and to thereby prevent the same from becoming overheated by the conduction of heat from the incandescent wire. The wire loops which form the incandescent members of the invention as illustrated in Figs. 4: 5, and 6 are preferably constructed of sections, one of which is a relatively good conductor of electricity, while the other is of relatively high resistance. The ends of the loop are anchored in the upstanding lugs 22 and :it

has. been found in practice that, the same may be securely fastened in said lugs by support theupper end of the section 26 in such a manner as to impose a slight tension 1 [upon the latter and thereby maintain the same at all times in a vertical position. The

supporting members 21 are preferably .ar-.

ranged in the manner-illustrated in'Fig. 4: so that the electric current will pass through said wires inseries. As shown in Fig. 4 the supports 21 are arranged in staggered relation so that the ends of the successive sup ports overlap just enough to bring the wires connecting said ends into planes parallel to the, direction of movement of the strands of roving- The sections 26 being of course on the front side so thatthe wandering fibers w'illbe burned off upon-contact with said incandescent sections 26.

Another form of the invention is illustratedin Figs. 7 and 8 in which the incandescent wires are supported upon an insulating body or post, the incandescent section of the wire being preferably partially embedded in a vertical groove extending along the side of the insulating member. As illustrated in these figures theinsulating memer consists preferably of a cylindrical post 30 having a lateral extension at its bottom 31 provided with an aperture adapted to receive a screw 32 to secure the same to the bar 13. The cylindrical member is preferably provided with a vertical aperture 33 adapted to receive a suitable conductor of copper or brass wire 34 and if desired the wire may be cast within the insulating member. The outer portion of the cylindrical insulating member is preferably provided with a groove 35 adapted to partially inclose a section of wire 36 of relatively high resistance such as nichrome aforesaid. The conductors'34c and 3? may be led from the base of the cylindrical insulating members to suitable binding posts 37 whereby they may be arranged in series as aforesaid.

When the device as illustrated in Figs. 5 and 6 is placed in position upon the winding frames the posts will be mounted intermediate the strands of roving, the incandescent wires 36 being in planes intermediate of and substantially equidistant from the edges of the adjacent strands. In the operation of the machine the insulating members or posts will prevent the edges of the strands from being suiiieiently deflected to encounter the wires and be singed thereby but any wandering fiber which extends from one strand to another will during its movement toward the winding mechanism encounter the incandescent member 36 and be severed in the manner aforesaid.

It is to be understood that the embodiments of the invention shown herein are illustrative merely and that the same may be incorporated in other constructions. It is also to be understood that this invention may be utilized in other relations than those described herein since it is adapted to maintain strands of any suitable material which are directed from one part of the machine to another or from one machine to another in a separated condition. It will also be obvious that the form of incandescent members herein are adapted to different uses, that illustrated in Figs. 7 and 8 being particularly adapted to be used in connection with. singeing machinessince whatever the arrangen'lent of the insulating member the incandescent wire will be supported through its length and thereby-maintained in uniform relation to the material being singed notwithstanding the expansion by the heat required to raise the same to incandescence and further by reason of the fact that circumferential adjustment of the incandescent member would provide means for supporting the fiber in such a position that it may be caused to travel in any degree of proximity to the incandescent member.
